ABSTRACT
Bacteria demonstrate their ability to live socially and to interact with other colonies by establishing an intercellular communication through a mechanism called quorum sensing (QS). This cellular communication can facilitate the bacterial community to respond to each other, carry out metabolism, density information, and activity by recognizing signaling molecules in the form of pheromones or autoinducers. This review discussed the interaction between bacteria in abandoned tin mining pit waters which was described as a quorum sensing system for the bacteria and its role to encounter the pH value changes. The member population of Phylum Proteobacteria looked very central in the abandoned tin mining pit because its dominance in all age of the pit with a high number. Proteobacteria were able to synergize with the other of acidophilic bacteria to carried out the oxidation activities of the elements that have an impact on the formation of acidic pH conditions (pH = 3). Proteobacteria also showed indications of being able to encourage the emergence of important functions of Bacteroidetes, Planctomycetes, Cyanobacteria, Spirochaeta, and other bacteria by decomposing organic matter or other metabolic activities so as to increased the pH value of ex-tin minig pits enironments to neutral (pH = 7). Community structure of bacteria showed bacteria composition was different for each pits water with chronosequence. Pits in age < 1 year with pH about 3 were dominated Phylum Proteobacteria about 30%, pits in age 5-10 year with pH about 3 were dominated Phylum Bacteroidetes about > 30%, and pits in age > 15 year with pH about 7 were dominated Phylum Planctomycetes about > 37%. The interaction of bacteria through quorum sensing is expected to be useful in the process of environmental management of post-tin mining waters to produce an aquatic ecosystem that is more beneficial to humans and other aquatic organisms.
